摘要

A considerable fund of information concerning the effects of substituents on reactions of given groups in the benzene series is availableS2 On the basis of these data, it is possible to correlate such effects by a simple mathematical treatment, and to express the magnitude of such effects by unique constants. Thus a constant, Q, measures a change in electron density produced by a substituent, and a second constant, p, measures the susceptibility ...
